Have you ever seen a big Refrema with replenished chemistry? Tanks that are three feet deep and hold gallons of developer. These machines are large and difficult to alter once they're set up. The replenished developer is tightly controlled with control strips (if done right). To keep the balance between the bromides and other byproducts, a certain amount of replenisher is added to the system. Containers that hold the chemicals sit on racks and they are replenished on the fly.
The racks that hold the film, which are also about 3 feet tall, are moved mechanically from tank to tank: developer, stop bath, fixer, rinse, hypo clear, wash, dry. It's a very impressive system, and when done right the results are amazing.

Look one up online, and there's your answer.
